Now using Scala 2.11.0!
-----------------------

We have switched to scala 2.11.0, and therefore, you will get a new
build.sbt! You don't need to do anything else if you already installed
the project -- just run sbt!
We also introduce another type: the byte string! Just say `Bytes(...)'
to create one! You can also create binary function literals using
`Func(...)' (now you have the equivalent of the TI-89 Exec!)
Two new commands have been added: $:gettype(val) and $:seq(a1, a2)
(or a1 === a2).
Due to numerous complaints, For loops now run on half-open intervals
rather than closed.
